I went camping in Drumheller Provincial Park, Alberta, Canada where I was lucky to witness a very short lived aurora display during the early hours of June 2nd, 2018 just after midnight. I drove just SW of Drumheller and positioned myself just in back of the Horseshoe Canyon facing north. Despite the high hopes and following the aurora forecast we didn’t get an amazing show, not even a G1 storm as predicted, just a K3- to a K4 where Aurora was dancing shy for less than an hour. The solar wind was blowing hard between 600-700 Km/sec, the hemispheric power was below 40Gigawatt with some negative Bz component around -5nT and unfortunately the sum of these parameters did not crack to a G1 storm, staying between a K3 and K4 during the short show. Anyway, with the solar minimum here and during the summer hours, such a light breeze of aurora is more than welcome, specially when she was associated with a much elusive Milky Way, some fast moving clouds and not at least with almost midnight sun, creating a very nice contrast of colors of the blueish-purple pillars the grayish clouds and the orange glow of the midnight sun.

The actual storm arrived during the day what you witnessed was the tail end of the impact.
